<span>Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5</span>
We can set up a proportion to solve this problem as follows:
height of the model/width of the model= height of the actual/width of the actual
24/18=60/x
Cross multiply,
24x=18*60
24x=1080
x=45 ft.
Therefore the answer is 45 ft.
